There are two sighting vanes which are aimed at a terrestrial object with the bearing
read off the compass card. These bearings are compared to the vessel's compass heading which then gives the magnetic bearing
to the object. Bearings of two objects, taken sequentially, will fix the vessel's position. Similar observations of a
rising or setting sun when on the prime vertical allow for determining compass error. A third arm, with a polished
black glass reflector, allow similar sights to be taken of celestial bodies when on the horizon.
CONDITION: Except the lock for the sighting vanes
not engaging, some minor dents in the brass hood and on the lower black shroud, and some loss of paint in a few
spots, the item is in like new condition and may be considered of exceptional quality. In the base is a lead weight
and receptacle with light bulb.
